The Federal Housing Finance Agency should seriously reassess its regulations which permit the 12 Federal Home Loan Banks to build large unsecured, credit portfolios “that may produce unreasonable risk,” according to an audit by the agency’s official watchdog.

Unsecured credit extensions to European institutions swelled from $66 billion at the end of 2008 to more than $120 billion by early 2011
